hi,

i tried that win2k option and qemu still fails with or without it. :-/

i loaded up aio(4) module and while displaying the following ...

Nov 12 01:24:38 mb-aw1n-bsd kernel: WARNING: Network stack Giant-free,
but aio requires Giant.
Nov 12 01:24:38 mb-aw1n-bsd kernel: Consider adding 'options
NET_WITH_GIANT' or setting debug.mpsafenet=0

... it actually helped my case and now i'm curiously installing
winblows.. ;o)

many thanks !!
